Zoo Zoo Zirconia crown ua nyob rau hauv Suav teb

Dab tsi yog qhov zoo ntawm zirconia crowns?

Zirconia cov yas, tseem hu ua Zirconia tag nrho cov ceramic nrog, muab ntau ntau yam sib txawv ntawm lwm hom kev kho hniav. Ntawm no yog cov ncauj lus kom ntxaws piav txog lawv cov txiaj ntsig tshwj xeeb:

Kev ua kom zoo nkauj

Zirconia crowns muaj koob meej rau lawv cov kev thov kom zoo nkauj zoo nkauj. Cov khoom siv muaj lub siab ua haujlwm siab thiab ua kom zoo hloov pauv, ze rau cov xim thiab cov tsos ntawm cov hniav ntuj. Qhov no tso cai rau kev sib koom ua ke nrog cov creditional nrog cov neeg ib puag ncig, muab kev txhim kho lub ntuj thiab kev txhim kho zoo nkauj. Cov kev tshawb fawb soj ntsuam tau pom tias zirconia cov txiaj ntsig zoo rau cov xim sib piv thiab ua kom pom kev sib piv rau cov hlau uas muaj metallic hue lossis opacity.

Biocompatibility

Zirconia yog cov khoom siv hauv roj ntsha, lub ntsiab lus nws tsis hnov ​​zoo nrog lossis ua rau cov nqaij ib puag ncig. Nws ua kom pom kev zoo biocompatibility nrog ob lub ntsej muag nyuaj thiab cov tshuaj pleev xim zoo tshaj plaws rau cov neeg mob sib koom ua ke lossis cov neeg nrhiav cov khoom siv hlau. Tsis zoo li ib co hlau hlau, zirconia tsis tso cov hlau ions rau hauv qhov chaw ntawm qhov ncauj, uas tuaj yeem ua rau cov neeg tsis zoo. Ntau cov kev tshawb fawb tau lees paub txog kev nyab xeeb thiab biocompatiet ntawm zirconia cov yas, hais txog lawv cov kev haum rau kev siv hauv kev kho hniav ntev hauv kev kho hniav.

Yam ruaj khov

Ib qho ntawm cov txiaj ntsig zoo tshaj plaws ntawm cov kab mob zirconia yog lawv qhov tshwj xeeb depability. Zirconia yog lub zog siab-ua kom muaj zog nrog lub zog ntawm 900 rau 1400 MPa, uas yog qhov zoo dua rau cov tsoos oposion rau ib txwm muaj ntawm qee cov hlau. Qhov kev kho tshuab hluav taws xob zoo no ua rau zirconia crowns heev tiv taus thiab hnav, txawm tias nyob rau hauv cov khoom hnyav. Raws li qhov tshwm sim, lawv tau zoo tshwj xeeb rau kev kho vaj evplior, xws li cov pob txha caj qaum thiab ntau tus choj, qhov twg ruaj khov yog qhov ntsuas tsis tau. Kev tshawb fawb hauv kev tshawb nrhiav ntev ntev tau pom tias muaj kev ruaj ntseg thiab muaj peev xwm ntawm cov zirconia crowns, nrog ntau yam ntev tshaj plaws nrog kev saib xyuas kom zoo.
